John Q., howdy
Just now pulling out of the food coma brought on by Thanksgiving overindulgence......blood sugars approaching normal...must be time for a turkey sandwich and apple pie!
Back on that global warming thing....I couldn't find, after a cursory search, a straight-forward plot of historic temperatures, but I thought you might find this interesting.

"However, computer simulations of Cretaceous climate indicate that radiative warming caused by increased greenhouse gas concentrations (principally CO2) [HN12] were more important than paleogeography in explaining Cretaceous global warmth (9). Estimates of Cretaceous pCO2 generally range from four to eight times preindustrial values (10), and some intervals, such as the Turonian-Coniacian (1), may have exceeded this amount severalfold (perhaps explaining the warming spike observed for that time). Climate models have revealed, however, that although CO2-induced warming can approximate globally averaged temperatures for the Cretaceous, the models predict steeper latitudinal temperature gradients (both warmer tropics and colder poles) than geologic data seem to allow. This has led some to suggest that the oceans played a greater role in transporting heat from the tropics to the poles than they do today, particularly through sinking of dense, saline waters formed in restricted low-latitude basins (9). However, Sloan et al. (11) [HN13] calculated that doubling the ocean heat transport to balance the energy budget for the warm climate of the early Eocene would require a mechanistically prohibitive poleward flow of warm, saline water masses. These authors concluded that either the oceanic processes of a greenhouse world were very different from those of the present or some other mechanisms must be used to explain the low equator-to-pole temperature differences. "
So....global warming might bring back the dinosaurs and lay the groundwork for the next layer of oil and gas. Forget B2K (Boom 2000), let's talk about B2MM.
